Confidence: limited - limited rating history.Last refreshed Jun 21, 2026. Data-computed, not a hands-on test. Compiled by the ProductDome Research Team.
Overview
A step-thru folding fat-tire ebike with a 500W peak motor, 48V removable battery, and a 20 mph top speed, built around SGS certification to UL2849. Suits riders who want a compact bike that folds down for a car trunk or small storage space.
Vivi lists both a 350W continuous rating and a 500W peak figure for the motor, so treat 500W as the ceiling rather than the steady output. The 16x3 inch fat tires and step-thru frame favor stability over speed, and the bike ships 85 percent assembled with roughly 30 minutes of setup left to the buyer.
- 500W peak motor, 20 mph top speed
- 48V 7.8Ah removable battery with BMS
- 16 x 3.0 inch puncture-resistant fat tires
- Folding step-thru frame, 85 percent pre-assembled
Who it's for
Fits commuters or casual riders who want a folding bike that handles sand, gravel or light snow at a modest pace. Not the choice for anyone chasing top-end speed or expecting minimal assembly.
What buyers say
From Amazon customer reviews.
One buyer praised the acceleration, handling and durability as matching the advertised specs, while another received a bike with a throttle that never worked and found no troubleshooting instructions included, leaving them stuck with a bike they could not easily return.
Strengths and trade-offs
Drawn from this product's published specifications.
- Folds and fits in a car trunk
- Puncture-resistant fat tires grip sand, gravel and snow
- SGS certified to UL2849 for battery safety
- Arrives 85 percent pre-assembled
- Small review pool, reliability largely unconfirmed
- One buyer's throttle failed with no troubleshooting guide
Performance notes
The 48V 7.8Ah battery charges in 4 to 6 hours and pairs with a BMS for overcharge protection, with Vivi citing a 20 to 50 mile range depending on assist level. Top speed tops out at 20 mph on the highest of the 7 speed settings, and the puncture-resistant fat tires are the main line of defense on rough terrain rather than any suspension system.
